Comment (by JeremyRand):
I think I have fixes for both (1) and (2). For (1), decreasing the
relevant timeout from 45 seconds to 15 seconds seems to improve the
initial connection delay quite a lot without causing timeouts when a Tor
circuit is bad. I haven't tried with pluggable transports enabled though;
I wonder if the public PT bridges will be slow enough to cause 15 seconds
to be too short to open a TCP connection. For (2), I applied a similar
change to the one I suggested in the upstream Electrum bug.
Interestingly, I just found a bug in ncdns that also causes (2) even once
the Electrum-NMC JSON-RPC error code is correct. The fixes will be pushed
shortly.
Thanks for catching these issues!
As an aside, note that even once the fix for (2) is applied, Electrum-NMC
will try 3 times, using a different server each time, before deciding that
a name doesn't exist. It does this so that a single malicious server
can't hide the existence of names. (The SPV proofs returned by a server
only prove inclusion, not non-inclusion; adding non-inclusion SPV proofs
is something that's on our to-do list; once that's implemented, then we'll
be able to drop the multiple-server lookups for nonexistent names.) This
doesn't cause a significant delay on its own though.
